Physematium oreganum, the Oregon cliff fern, is a deciduous perennial fern in the family Woodsiaceae. This plant is native to a large part of the western and northern United States and much of Canada. [3] [4] [5]
Physematium oreganum leaves (fronds) are twice pinnate to pinnate-pinnatifid (second leaf division not complete to base) growing from a short scaly rhizome. Individual plants sometimes appear as a single clump, but may form an elongated mass when the rhizome is longer. The leaves are up to 25 cm long and 12 cm wide and are held upright to angled. The rachis may have sparse very short glandular hairs, but it is distinguishable from the similar Physematium scopulinum by a lack of long hairs on the rachis (stem). Small round sori on the underside of pinnae are initially partly covered with a narrowly lobed indusium. [4]
Physematium oreganum is usually found in open rocky areas and on rock outcrops. [5] It grows widely in the western United States and southwestern Canada, and is present in more scattered locations further east. [6]
Anthriscus sylvestris, known as cow parsley, wild chervil, wild beaked parsley, Queen Anne's lace or keck, is a herbaceous biennial or short-lived perennial plant in the family Apiaceae (Umbelliferae). It is also sometimes called mother-die, a name that is also applied to the common hawthorn. It is native to Europe, western Asia and northwestern Africa. It is related to other diverse members of Apiaceae, such as parsley, carrot, hemlock and hogweed. It is often confused with Daucus carota, another member of the Apiaceae also known as "Queen Anne's lace" or "wild carrot".

Aspidotis densa is a species of fern in the Cheilanthoid subfamily, known by the common name Indian's dream or Serpentine fern or dense lace fern. It is native to the west coast of North America from British Columbia to California and east to the Rocky Mountains in Idaho, Montana, and Wyoming; there is a disjunct population on serpentine soils in Quebec.
Campanula scabrella is a species of bellflower known by the common name rough bellflower. It is native to the mountains of the western United States, where it grows in talus and other rocky alpine habitat. This is a tough perennial herb growing in a clump from a woody rhizome and rarely exceeding 5 centimeters in height. The stiff leaves are linear to narrowly oval in shape and about 3 centimeters long, borne on winged petioles. The leaves are covered with very short appressed pale hairs. The small funnel-shaped flower is just under a centimeter long and pale blue or lavender in color, arising from the leaf clump on an erect pedicel about a centimeter tall.
Myriopteris gracillima, formerly known as Cheilanthes gracillima, is a species of lip fern known by the common name lace lip fern. It is native to western North America, where it grows in rocky habitat from British Columbia to California to Montana.

Adiantum viridimontanum, commonly known as Green Mountain maidenhair fern, is a fern found only in outcrops of serpentine rock in New England and Eastern Canada. The leaf blade is cut into finger-like segments, themselves once-divided, which are borne on the outer side of a curved, dark, glossy rachis. These finger-like segments are not individual leaves, but parts of a single compound leaf. The "fingers" may be drooping or erect, depending on whether the individual fern grows in shade or sunlight. Spores are borne under false indusia at the edge of the subdivisions of the leaf, a characteristic unique to the genus Adiantum.

Unlike many members of its genus, its leaves have a few hairs on upper and lower surfaces, or lack them entirely. One of the cheilanthoid ferns, it was usually classified in the genus Cheilanthes as Cheilanthes aemula until 2013, when the genus Myriopteris was again recognized as separate from Cheilanthes. It typically grows on limestone rock.
Myriopteris aurea, the golden lip fern or Bonaire lip fern, is a moderately-sized fern native to the Americas, a member of the family Pteridaceae. Unlike many members of its genus, its leaf is only modestly dissected into lobed leaflets (pinnae), which are hairy both above and below. One of the cheilanthoid ferns, until 2013 it was classified in the genus Cheilanthes as Cheilanthes bonariensis, when the genus Myriopteris was again recognized as separate from Cheilanthes. It typically grows on dry, rocky slopes, and ranges from Mexico, where it is common and widespread, and the southwestern United States south and east through Central and South America as far as Chile and Argentina.
